'WENDOVJ Application filed April 12,

My invention relates to steel windows and especially to a steel sash section having` pivotal means to be disposed at an angle to the plane ot the window. 1n sashes ot the -type to which the invention relates, the

roller pivot has a pern'iancnt iorm and doe-'i not permit or' adjustment so that the pivot means cannot be varied to suit windows slightly varying' in width and the pivot when the sash .is in piumb, r when it is dented or winding', causes the window to bind.

The general object of my invention is to provide pivot means for a sash section so constructed and arranged as to permit ot adjustment ot the pivot to vary the total transverse dimensions ot the window at the pivot line and to permit of the swinging oi the sash section even though the latter be bent or otherwise deitorined.

'lhe nature ot i'ny invention and its distinguishing iteatures and ai'lvautagres will more clearly appear as the description pro- Coeds.

Reference is to be had to the accompanying drawings 'forming a part of this speciiication, it being' understood that the drawr ings are merely illustrative ot one example of the invention.

Figure 1 is a 'trout elevation showingl a swingable sash section equipped with my invention and portions ot permanently mountn ed sash sections above and below the swingable sash section.

Figure 2 is a side view of the sash of the window, the near vertical channel bar ot the window frame being' omitted so that the sash section and its novel appurtenances appear in edge view with the far vertical tramo bar in elevation.

Figure 3 is a detail in vertical section at one ot the pivots;

Figure 11 is an end view at one end ot a pivoting unit.

Figure 5 is a view at the opposite end ot the pivot unit. l

In the illustrated example Ot my invention, the numeral indicates a movable sash section; 11 and 12, upper and lower iixed sash sections; and 13 indicates the vertical channel bars or jambs ot the window trame.

The sash section 10 is provided with a unii for pivotally mounting' the same each side. The unit comprises a transverse pivot pin 1i supported in spaced upright members 15,

16 rising from a base plate 17 which is riveted to the meeting rail 18 of said sash section. rPhe pivot pin 14 has a head 19 at the outer end thereof disposed in a roller socket 20 which is adapted to be disposed in the trame bar 18 wiich ot chinnei form. A spring` 21 is coiled about pivot pin 111 between the roller 2O and the adjacent upright members 1G which constitutes a fixed abutment tor the spring. The spring;` 21

permits of the roller 20 being, brought to-iv ward or tromthe abutment 16 tor adjusting' the pivotand tor emplacing the relier 2O .in the channeiframe bar 13. ,The inner end ot the pivot pin 14 which passes through the uprightmember 15 is adapted to be tastened for holding` the pin 14 in adjusted position, a set screw 22 in member 15 being provided 'for the purpose.

By loosening the set screw 22 and releasing the pin 14, said pin may be moved outward or :inward to accommodate itself to the window 'traine conditions and then with the two opposite rollers 2O at the respective sides ot' the sash section 10 in contact with the vertical frame bars 18, the set screw is' fastened to hold the pin 1st in given adjustment.

Braces 23 are provided 'or the sash sec tion 10 at opposite sides, said braces being' Apivotally secured at their upper ends as at 24 to said sash section and pivoted at the lower ends as atQ to the channel bars 13. A. side or flange of each of said channel bars is cut away to afford clearance for the swinging` of the braces to and 'from a position alongside the web of the channel bars 13.

l/Vith the sash section 10 equipped with the pivot units and braces as described, the sash may be moved outward at an angle to the plane ot the window `trame shown in Figure 2, the rollers Q() being' tree to travel in the bars 13. When the window is swung` inward into the plane ot the upper and lower permanent sections 11 and 12. the brace 23 folds along' the sides o'lf' the sash section 10.

I would state furthermore that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit ot the invention. l

Having` thus described my invention, I claim:

1. 1n a window, a trame having vertical channel bars at the sides, a sash section disposed between said vertical channel bars, transversely disposed pivot pins, means on the top bar of said section in which said pins are supported for inward and outward adjustment, means to secure the pivot pins in variously adjusted positions, rollers on said pivot pins at the outer ends and adapted to travel in the Vertical channel bars, springs coiled about said pins and normally tending to press said rollers outwardly, and braces pivoted at their upper ends to said sash section at 'the sides and having members at their lower ends extending into said channel bars.

2. A Window sash section adapted to be disposed in a window trame7 pivot pins at each side of said sash at the top7 means mounting said pins and permitting a longitudinal adjustment thereof, and means tor locking the pins in adjusted positions.

3. A Window sash section adapted to be disposed in a Window frame, pivot pins at each side of said sash at the top7 means mounting said pins and pern'iitting a longitudinal adjustment thereof and means for locking the pins in adjusted positions; together with rollers on said pins adapted to have guided movement in the sides of the Window frame.

4L. A pivot unit adapted to be secured to a Window sash and including a base, vertical members on said base, a pivot pin adjustable longitudinally in said members, and means to secure said pin in adjusted position.

A pivot pin for a sash, comprising a base plate having spaced Vertical apc-rtured members,' a pin mounted to slide in the apertures oi' said members, a. roller mounted to slide and turn on the outer end ol' the pin, a spring on the pin and having one end engaging the outer member of the base plate and the other end engaging the roller, and a screw mounted in the inner member of the base plate and engaging said pin.
